PDFBOX-4421: fix bugs to support and enable AES 128 encryption, as suggested by
Christian Appl:
- get actual key length from default crypt filter dict (PDFBox was using
default 40)
- use SHA1 digest for V 4

> Follow-up of PDFBOX-4413. AES256 works for public key crypto, but AES128
> doesn't when the file is generated by an external software. (local tests
> work) We should at least get the decryption to work.
